My 82'300TDT is running hotter than it used to. I don't think the fan is working. Is there a way to test the electric fan motor in front of the radiators by splicing in a wire to the fans +red wire and connecting the spliced in wire to some place under the hood? Maybe the fuse it runs on? I touched it (with the ignition on) to the battery positive+ and got a violent spark. I tried it on the fuse box (on the wrong fuse)not the one for the fan,etc. and blew that fuse. I would like to wire it to operate manual by putting a electric on/off switch under the dash area, but I don't know even if the fan motor works. Thank you for any advice concerning this question.
